According to the screenshot, you are running GNOME Fallback (in Ubuntu it is known also as GNOME Classic) instead of GNOME Shell.

Next time you log in, select 'GNOME' instead of 'GNOME Classic'. If still fails, it is because there is an issue with 3D in your driver. When it is not possible to run 3D, GNOME switches to GNOME Fallback. You can also check ~/.xsession-errors for more clues.
